has anyone else had the same problem as what ive got with my daughters w850. its on the 3 network and was working fine until i tryed to unlock it via xs++ and netools ive flashed it a few times and its still here. the problem is it turns it self off and back on every 20-30 secs also its showing signal but wont conect to any networks? ive run sony ericsson update and its still the same,i also took it to a mobile phone shop yesterday and he just looked at it quickly and said its like that as its been reported lost/stolen but the thing is ive phoned up 3 today and had a good chat with them and gave them the imei number and its showing the phone if clear to use. im at my wits end now as this was suposed to be my daughters birthday present....
